Heya ! Here's my complete review (that I used to rate the game)
Visual
The game doesn't look necessarily bad, but as said before, the red is too red, it hurts my eyes :(
And the different assets don't really match in style, imo. Also, try to always keep in mind that there are some people out there who are colorblind, and it's often a good idea to try and have maximum contrast to reduce the impact on them :)
Audio
The game misses a BGM, but the SFX used in the game fits it perfectly :)
Tutorials
Unfortunately none :(
Gameplay
- The bonuses/maluses you can get change the gameplay a bit, and that's great!
- The game is challenging during the first minutes, I've died multiple times before understanding how to survive, that's great!
- Maybe a bit too slow when there are only 1-2 survivors. It would be nice to have a visible counter and an arrow pointing the the remaining ones after x seconds.
Fun
The game is moderately fun because of the pace. I like the beginning but not the end of the waves.
Bugs
I don't know if that's actually a bug, but I couldn't finish the second wave even if no one was alive.
Theme
In the theme, it's fine by me :)
